Tobirama in Izuna's funeral

Tobirama really screwed things up - created Edo Tensei, killed Madara's brother without blinking, segregated the Uchiha out of some sense of paranoia, picked the worst person possible to run Konoha's black-ops(Danzo) just before he went off and died.

Tobirama and Izuna were the same. They both had hatred torwards each other's clans. Uchihas killed many Senjus and Senjus killed many Uchihas. Their big brothers created bond with each other but those two were influenced by their families so they both hated each other's clans. If Izuna lived longer then he would hate the Senju like Tobirama to the Uchihas.

I watched Naruto last night with Edo Tobirama vs. Madara. Did Madara ever go to town on Tobirama with those Black Chakra Rods. Then Madara said something like, "You're not even worth it cause you're already dead."
